Pygame碰撞检测:AttributeError

提问于

我一直在反对这个问题 . 我正在尝试用PyGame制作一款游戏,然后我开始碰撞并且已经卡住了一段时间并检查了几个线程 .

这是我的代码(删除了其他方法和条件语句,但保留了相关部分) . 我对错误感到有点困惑,因为我在两个类init中都执行了self.imageRect = self.image.get_rect(),但是我有这个错误 . 错误具体是:
当程序试图在dog类中执行碰撞检测部分时,“ AttributeError: 'Pebble'对象没有属性'rect'” . 我做错了什么?

pygame.init()
clock = pygame.time.Clock() # fps clock

screenSize = WIDTH, HEIGHT = [800, 600]
screen = pygame.display.set_mode(screenSize)

bgColorRGB = [153, 204, 255]
background.fill(bgColorRGB)


pebbleGroup = pygame.sprite.Group()
pebbleSingle = pygame.sprite.GroupSingle() 
dogSingle = pygame.sprite.GroupSingle()

    它期待 Sprite.rect ,所以改变

    self.imageRect = self.image.get_rect()
    #to
    self.rect = self.image.get_rect()
    

    注意

    self.imageWidth = self.image.get_width()
    self.imageHeight = self.image.get_height()
    self.imageRect.left, self.imageRect.top = location
    

    这些不是必需的,因为rect具有许多属性,如 self.rect.widthself.rect.topleft = location . 另一个有用的是 centerx .
